The billing model you choose for your charging network shapes more than how you collect money. It shapes which customer relationships you can build, what kinds of partners you can work with, and how your revenue scales as the network grows.
This piece covers every billing model available on the AMPECO platform and the business situation each one fits best. The goal is to help you make this decision with full information, not discover after the fact that your software can’t support the partnership you just signed.
Billing Strategy Is a Business Decision, Not a Platform Setting
The billing approach you choose reflects an assumption about your customer. A model that requires drivers to pre-authorize funds before a session assumes they’re comfortable reserving money on a credit card and that your network draws the kind of customers who expect that process. A model with no payment requirement assumes the operator is absorbing the cost — and has a solid business reason for doing so.
Get the model wrong and you create friction in exactly the wrong place. A pre-authorization requirement on a destination charging network, say at a hotel or shopping center, adds unnecessary barriers for drivers who just want to plug in. An open-access model at a public fast-charging hub exposes you to sessions you’ll struggle to collect payment for.
Billing also shapes what commercial relationships you can build. A standard per-session model doesn’t accommodate an employer who wants to cover their employees’ charging and settle once a month. A subscription plan, on the other hand, can be the reason a fleet operator stays with your network rather than chasing a better rate.
Many CPOs start with the simplest configuration available — card on file, billed at session end — and revisit that decision 18 months later when a new partnership doesn’t fit the billing structure they’re running. It’s a pattern we see often: the billing setup that made sense at launch quietly becomes a ceiling on the partnerships you can build.
The more useful question to ask during platform selection: does this software support where you’re going, not just where you’re starting? On AMPECO, different users on the same network can operate under entirely different billing models at the same time, so you’re never forced to make one approach work for everyone.
The Main Ways EV Drivers Can Pay on Your Network
AMPECO supports several distinct payment approaches. Which ones you activate depends on your customer base, your commercial model, and how much friction is appropriate — or not — at the point of charge.
Post-paid, card on file. The driver registers a payment method, starts a session, and is billed when it ends. This is the most common model for public charging because it keeps friction at session start to zero. The card is charged after the fact, and if a payment fails, the platform retries automatically.
Pre-authorized. Before the session begins, the platform places a hold on a set amount on the driver’s card. The session runs until the pre-authorized limit is approached, at which point it stops. If the session costs less than the reserved amount, the remainder is returned. This model gives operators more cost predictability and is well-suited to fast charging, where session costs can climb quickly.
Balance and wallet. Drivers pre-load funds into a balance and pay from it during sessions. The platform can auto-top-up the wallet when it drops below a set threshold, preventing sessions from being interrupted by insufficient funds. This model suits closed networks, fleets, and mobility services where controlled cash flow matters more than frictionless onboarding.
Ad hoc, payment terminal. Drivers pay by tapping a contactless card or device directly at the charge point — no account, no app, no pre-registered payment method required. This is the right option for high-traffic public locations where removing the registration barrier is a priority: occasional users, visitors, or anyone who won’t return regularly enough to justify setting up an account.
Coupons and vouchers. Drivers redeem a voucher to add balance or cover session costs. Commonly used for promotional campaigns, employee benefit programs, or partnerships where a third party pre-purchases charging credit and distributes it to their users. Vouchers integrate alongside most primary billing strategies rather than replacing them.
Open access. No card, balance, or registration required. The operator absorbs the session cost. This works for destination charging where free access is a deliberate commercial decision — hotel guests, retail customers, residents with charging included in their tenancy. It requires a clear rationale; it’s not a substitute for thinking through payment setup.
Subscriptions work differently enough from all of the above that they warrant their own section.
When Subscriptions Make More Sense Than Charging Per Session
Subscriptions make sense once you have a repeat user base to build on. For drivers who charge occasionally or unpredictably, per-session billing works fine. For others — employees who charge at work daily, fleet operators managing predictable vehicle schedules, residents in a building with shared charging — it creates administrative overhead and removes any sense of value from regular use.
Subscription plans address this by replacing per-session transactions with a recurring fee structure. Pre-paid subscriptions are straightforward: the driver pays upfront for a defined period, then charges within the plan’s terms. Revenue is collected up front. The charging volume stays within the plan’s limits. This works when your customers charge regularly and you want revenue locked in rather than tied to usage.
Post-paid subscriptions flip the sequence: drivers charge throughout the period and are billed afterward based on a defined billing cycle. AMPECO offers two cycle options. The cycle can start on the date the driver subscribes, giving each driver a consistent personal billing rhythm tied to their join date. Alternatively, it can align with calendar months, which simplifies reconciliation when managing many accounts — one billing run, one batch of invoices, the same dates every month.
A single AMPECO network can run both pre-paid and post-paid subscription plans at the same time, alongside drivers on per-session billing. The platform doesn’t require a uniform approach across your entire user base.
Corporate Billing: When a Partner Pays for the Driver’s Charging
Corporate billing becomes relevant when you’re actively building — or want to attract — business partnerships. A logistics company, for example, wants to cover employee charging as a staff benefit, but they need one invoice a month, not one per driver. Corporate billing closes that gap.
The model changes the payment relationship at a structural level. Instead of the driver paying for their own sessions, a partner — an employer, a commercial property operator, a fleet management company — picks up the tab. The CPO invoices the partner on a settlement basis rather than collecting payment from each individual driver. That shift in billing responsibility is what makes corporate billing a commercial model, not just a configuration option.
The arrangement is set up per partner, not network-wide. A CPO can have some partners operating under corporate billing, others on standard invoice terms, and general public drivers paying per session — all on the same platform. Each partner enrolled in corporate billing gets its own billing parameters.
Pool limit. The CPO sets a spending cap for the billing period. When reached, drivers fall back to their own payment method for the rest of the period. The limit is a pool cap — it applies across all drivers, not to each driver individually. This gives you a hard ceiling on exposure to any one partner.
Individual driver limits. Beyond the pool cap, the operator can define a spending limit per driver within the corporate account. On a large account, a small number of high-volume drivers can exhaust the pool before the period ends, leaving other enrolled drivers without coverage. Individual limits let a CPO offer corporate billing to a partner without ceding full control over how that budget is distributed.
Billing period. The billing period for a corporate account can be set to monthly, quarterly, semi-annual, or annual — whichever aligns with the partner’s own accounting and budget cycles. A company that manages charging as a quarterly cost center doesn’t want monthly settlement invoices creating reconciliation work. Matching the billing period to the partner’s finance rhythm reduces friction in the ongoing relationship.
Optional controls. A percentage discount can be applied to service fees billed to the corporate account — useful for reflecting a volume arrangement or incentivizing a strategic partnership. Corporate billing can also be restricted to the partner’s own charge points, so an employer or property manager covers charging costs only at their specific site rather than across the full public network.
The outcome of combining these controls is a billing model built for B2B relationships — one that gives CPOs the ability to structure partnerships with predictable economics on both sides.
Running More Than One Model at Once
Most networks don’t serve one type of customer. A CPO might operate public pay-per-use stations at a motorway stop, run a workplace charging program with a nearby corporate campus, and offer a subscription to frequent users at a residential complex nearby. Each of those relationships has different billing requirements, and expecting one configuration to serve all of them is a source of eventual friction.
AMPECO supports multiple billing models on a single tenant simultaneously. A driver enrolled in a corporate billing account pays through that arrangement. A subscribed driver pays through their plan. A casual visitor pays per session at the point of charge. These aren’t separate systems running in parallel — they’re different user configurations within the same platform. Adding a new billing model doesn’t affect drivers already on your network; new configurations apply to new users or specific invited segments.
The practical implication when evaluating a charging management platform: the question isn’t just whether it supports the billing model you need today. It’s whether it supports every model you might need across every type of customer and partner you plan to serve in the next few years. Changing billing infrastructure mid-operation is a project most CPOs would rather not plan. The cleaner approach is to choose a platform that doesn’t require it.
Start With the Business Model, Then Configure the Platform
Billing strategy deserves the time it rarely gets. The per-session options, the subscription structures, and the corporate billing model aren’t interchangeable — each one defines a different customer relationship, a different commercial arrangement, and a different set of operational commitments.
The platform you build on should be capable of supporting your most demanding billing scenario from the start, not just the simplest one you can get live quickly. A useful test during evaluation: can this platform run corporate billing, subscriptions, and per-session payments in parallel, without requiring a rebuild when your model changes or a new type of partner comes along?
If you’re just starting out, the most important thing to validate: does this platform let you add subscriptions and corporate billing later, without migration? That’s a good place to start the conversation.
